HARRY H. SCHLACK, OF PHILADELPHIA, PENNSYLVANIA.

MUSIC-TURNER.

Specification of Letters Patent.

Patented A11 17, 1915.,

Application filed September 1, 1914. Serial No. 859,669.

To all whom it may concern Be it known that I, HARRY I-I. SoHLAoK, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Music-Turners; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will en-. able others skilled in the art to which it appertains to make and use the same.

This invention relates to new and useful improvements in music leaf turners and has for its principal object to provide a device which may be easily and quickly operated without inconveniencing the user.

Another object of the invention is to pro vide an automatic device which will upon the pressure of a thumb-piece cause the leaf of the music to be turned thereby eliminating any necessity of manual operation.

A further object ofthe invention is to provide a simple and effective device by means of which the above named objects may be accomplished with the construction of metal or other suitable substance and which may be secured to a musical instrument without in any way injuring the same.

With these and other objects in view the invention consists in the combination and arrangement of parts which will be fully set forth in the following specification and in the accompanying drawing, in which:

Figure 1 is a front view in elevation of a music leaf turner constructed in accordance with this invention. Fig. 2 is an end view thereof showing the same as it would appear in place. Fig. 3 is an enlarged longitudinal sectional view illustrating the interior mechanism for turning the bars holding the music leaves. Fig. t is an enlarged detail sectional view taken on line lti of Fig. 1,

and Fig. 5 is an enlarged detailed sectional view taken on line 55 of Fig. 1.

Referring now to the drawings by characters of reference the numeral 1 designates the main supporting element of the device which is formed of a tubular member having secured to its upper end the sleeve 2 and at-its lower end the sleeve 3. Riveted or otherwise secured as at l near the lower end of the tubular member 1 is the clamp designated generally by the numeral 5 this clamp is formed of a flat piece of metal 6 having an internally screw threaded aperture formed near one end through which the shank 7 of the thumb screw 8 extends. This humb screw is provided at the end opposite the head with a suitable pad 9 which is swiveled thereon and arranged to engage the underside of the music rack as illustrated 111 Fig. 2. Extending upwardly from the member 6 is the portion 10 which terminates at its upper terminal in the angular extension 11 carrying the pad 12 which is riveted or otherwise secured thereto as at 13. It will thus be seen that a clamp is provided which will rigidly support the device in place on a music rack of any type without in any way injuring the same.

The lower sleeve 3 as heretofore referred to is provided with a pair of spaced ears 1% between which is pivoted the bell cranx 15. This bell crank is formed on one of its arms with a thumb portion 16 and the opposite terminal of the bell crank is arranged to engage the bottom face of the operating rod which will be more fully hereinafter described.

The operating rod hereinbefore referred to is designated by the numeral 17 and is arranged to rotate within the cylindrical standard 1 and said rod is provided at its upper terminal with a squared portion 18, a suitable coil spring 19 surrounds the rod and one end of the spring extends through the aperture 20 formed in the cylindrical upright 1 and thereby holds the spring against rotation. The opposite terminal of the spring is extended into an aperture formed in the rod 17 near the point where the squared portion 18 joins the same this spring is arranged to normally exert pull on the rod 17 to cause the same to turn clockwise.

A suitable sleeve 21 having formed therein a rectangular aperture 22 is provided and this sleeve is formed with an arm 28 carrying a depending lug 24. This depending lug is arranged to sink into the recess 25 formed in the upper end of the sleeve 2 to hold the arm 23 against movement. A suitable clamp member designated generally by the numeral 26 is carried by the arm intermediate its end and this clamp member comprises the body 27 which is formed with the ears 28. A pair of spaced ears 29 are struck from the arm and these cars are arranged to receive the pivoted end 30 by means of which the clamp member is pivotally secured to the arm. A suitable coil spring 81 is provided and is arranged to exert outward pressure against the upper portion of the body 27 and thereby cause the lower edge thereof to bear against the arm 23 with considerable pressure and firmly clamp the sheet of music in place. It is to be understood that when so desired a suitable bumper or buffer 35 may be secured to the free end of the arm 23 and this bumper is arranged to prevent the said arm from damaging or mar-ring the polished woodwork of the music rack upon which the device is used.

Slidable on the cylindrical upstanding member 1 is a suitable sleeve 31 which is formed with the laterally extending arm 32 these arms are formed along their lower edges with the flange 33 which forms a rest upon which the music is supported. A suitable thumb screw 3% extends transversely through the sleeve 31 and is arranged to hold the same in adjusted position on the upright 1 as clearly shown in the drawings.

It will be apparent from the foregoing that in use the music is placed on the rack and the sheet to be turned is clamped between the arm 23 and the clamp 26. hen it is desired to turn the music, pressure is applied against the thumb portion 16 which will cause the opposite end of the bell crank to rise thus pushing upwardly on the rod 17 and raising the sleeve 21 upwardly thereby bringing the extension 24 from engagement with the Walls of the recess 25. It will be apparent that under influence of the spring 19 the arm will be swung to the opposite position and thereby expose the reverse side of the sheetof music. From the foregoing it will be apparent that a particularly simple and effective music leaf turner is provided which will cause the music to be turned without in any way inconveniencing the user and a device is provided which may be easily and cheaply manufactured.

lVhile in the foregoing there has been shown and described the preferred embodiment of this invention it is to be understood that such changes in the combination and arrangement of parts as may fall within the scope of the claims may be resorted to without departing from the spirit and scope of the invention.

Having thus described the invention what is claimed as new, is

1. A music leaf turner including, a tubular upright a rod rotatable within the upright, a spring within the upright, said spring being connected to the upright and the rod and arranged to cause the rod to rotate, a releasing key carried at the lower terminal of the upright, an extension on the key operating against the rod to lift the same, an arm carried by the upper terminal of the rod, a lug on the arm arranged to hold the same against rotation and against the influence of the spring and a clamp carried by the arm and arranged to su port the sheet of music thereon when the evice is in use.

2. In a music leaf turner, a tubular upright, a sleeve slidable on the upright, a thumb screw to adjust the sleeve to various positions on said upright, lateral extensions on the sleeve, said lateral extensions being arranged to support the sheet of music when the device is in use, a rod rotatable within the upright, a spring arranged to rotate the rod, a squal'ed extension on the upper end of the rod, asleeve carried by the squared extension, an arm on the sleeve, the upper end of the upright being provided with a recess, a lug on the arm arranged to engage within the recess to hold the arm against rotation and prevent the rod from turning under the influence of the spring, and a releasing key carried by the lower terminal of the upright, said releasing key operating on the lower end of the rod to raise the same and thereby bring the lug from engagement with the walls of the recess and permit the arm to rotate.

In testimony whereof I. afiix my signature in presence of two witnesses.
